In the outskirts of Mtskheta are the ruins of Armaztsikhe fortress (3rd century BC). Armaztsikhe was the residence of the Kings of Iberia. This is one of the oldest cities of the Antique Era, which is not fully explored yet. It is also called like Georgian Acropolis. The Greek historian Dio Cassius mentioned this place in his book “The history of Rome”. He wrote that in 65 years BC, Roman Senator Gnaeus Pompeius invaded Iberia and reached this Acropolis too.
Archaeological investigations began in 1943 and three main cultures were identified: the oldest finds were dated to the 1st century BC to 2nd century AD, the central findings on the 3rd-5th centuries, and the latest to the 6th century. Consequently Armaztsikhe was destroyed by the Arabs in the 8th century. There are a royal sarcophagus, vestiges of the ramparts, a fortified tower and supporting pillars, foundation walls of the palace, a bath house, a wine cellar, a pre-Christian temple and a canal system.
The ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
